CVE-2023-6788: Metform Elementor Contact Form Builder <= 3.8.1 - Cross-Site Request Forgery

The Metform Elementor Contact Form Builder plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.8.1. This is due to missing or incorrect nonce validation on the contents function. This makes it possible for unauthenticated attackers to update the options "mf_hubsopt_token", "mf_hubsopt_refresh_token", "mf_hubsopt_token_type", and "mf_hubsopt_expires_in" via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This would allow an attacker to connect their own Hubspot account to a victim site's metform to obtain leads and contacts.

Security readout for executives and security teams

Plain-English summary

A vulnerable Metform WordPress plugin could let an attacker trick an administrator into changing the site's HubSpot integration. If successful, form leads and contacts could be routed to an attacker-controlled HubSpot account. This is a data exposure and integrity issue, not a server takeover based on the provided sources.

Executive priority

Treat this as a moderate-priority remediation for lead-generating WordPress sites. It can affect sales pipeline confidentiality and data integrity, but the known attack path requires administrator interaction and the provided sources do not confirm active exploitation.

Technical view

CVE-2023-6788 is a CSRF flaw in Metform Elementor Contact Form Builder through 3.8.1, tied to missing or incorrect nonce validation in the HubSpot contents function. The CVSS 3.1 score is 5.4, requiring user interaction by an administrator and allowing limited confidentiality and integrity impact.

Likely exposure

Exposure is most likely on WordPress sites running Metform versions up to and including 3.8.1 with HubSpot integration enabled or configured. The business risk is higher for sites collecting sales leads, customer inquiries, or regulated contact data through Metform forms.

Exploitation context

The sources do not show CISA KEV listing or active exploitation evidence. Exploitation requires tricking a site administrator into performing an action such as clicking a link, after which HubSpot token-related options could be changed to connect an attacker-controlled HubSpot account.

Researcher notes

Primary evidence points to missing or incorrect nonce validation in the HubSpot loader code and a WordPress Trac changeset addressing that area. The provided bundle does not independently name a fixed version, so validation should rely on vendor release guidance and installed-code review.

Mitigation direction

  • Identify WordPress sites running Metform and prioritize versions at or below 3.8.1.
  • Check vendor and WordPress plugin guidance for the fixed Metform release.
  • Upgrade Metform away from affected versions when a vendor-fixed build is available.
  • Review HubSpot integration settings for unexpected accounts or token changes.
  • Rotate HubSpot credentials if unauthorized integration changes are suspected.

Validation and detection

  • Inventory Metform plugin versions across managed WordPress sites.
  • Confirm whether each site uses the Metform HubSpot integration.
  • Review Metform settings for unexpected HubSpot account connections.
  • Check lead delivery paths for recent unexplained destination changes.
  • Monitor administrator activity around the publication and remediation dates.
